After defeating the real Grooveshark the RIAA is now determined to do the same to a copycat site that claims to be its reincarnation. However, new court documents reveal that the lawsuit may be the start of a broader anti-piracy strategy, with popular Internet services such as CloudFlare and LeaseWeb being dragged into the fight.

Earlier this month the long running lawsuit between the RIAA and Grooveshark came to an end.

Facing hundreds of millions in damages, the music streaming service settled the dispute for $50 million while offering an apology for the mistakes that had been made in the past.

The RIAA heralded the outcome as a major victory, but the joy didn’t last long. A few days after Grooveshark shut down unknown persons launched a new music service using the familiar Grooveshark brand.

Recognizing the new Grooveshark.io service as a considerable threat, the RIAA didn’t waste any time taking countermeasures. The group filed a sealed application for temporary restraining and seizure orders, targeting the site’s domain name and hosting services.

The court granted the RIAA’s request earlier this month and this week the documents were unsealed. They reveal how the music group intends to drag both Cloudflare and hosting provider LeaseWeb into the fight.

In his declaration, RIAA’s VP Online Anti-Piracy Mark McDevitt describes the new Grooveshark as a “blatantly illegal” site that hides its true location behind CloudFlare’s service.

“Because of the presence of CloudFlare’s servers, it is impossible to identify the location of the actual server supporting those aspects of the website absent the disclosure of this information by CloudFlare,” McDevitt writes (pdf).

While CloudFlare doesn’t host any of the infringing files, it’s accused of helping Grooveshark to evade detection. The RIAA alerted CloudFlare of this role early May and asked the company to take action, without the desired result.

“In response to this notice, CloudFlare informed the RIAA that it had notified the operator of the Grooveshark.io website of the RIAA’s complaint, but did not discontinue providing its services to the website,” McDevitt writes.

In an email seen by TF, CloudFlare informs the RIAA that it’s merely a pass-through provider, and that they’re not offering any hosting services.

“Please be aware CloudFlare is a network provider offering a reverse proxy, pass-through security service. We are not a hosting provider. CloudFlare does not control the content of our customers,” the company replied.

Even today, the new Grooveshark remains active on the Grooveshark.li domain name, and it’s still hiding behind CloudFlare. The site did lose its original domain name, which Namecheap seized after receiving the court order, but new domains are easily registered.

It’s unclear at this point whether CloudFlare is actively refusing to comply with the restraining order that’s targeted at Grooveshark’s Internet service providers, but the company’s counsel did attend a court hearing yesterday to discuss the matter.

Besides CloudFlare, the RIAA also names web company LeaseWeb, which they suspect of offering hosting services to the new Grooveshark. In its presentations to the court the RIAA lashes out hard against the Dutch company.

“LeaseWeb has a long history of hosting major pirate sites. For example, LeaseWeb once hosted the notorious (and now shuttered) pirate website ‘MegaUpload,’ which was the subject of the largest criminal copyright law enforcement action ever undertaken,” McDevitt writes.

“Other examples of LeaseWeb’s involvement with pirate sites are also well known in the antipiracy community,” he adds, after summing up several other examples.

Neither CloudFlare nor LeaseWeb are named as defendants, but the language used makes clear that the RIAA isn’t happy with how they respond to copyright complaints.

While Grooveshark.li is a relatively small fish, the case may set a crucial precedent for future anti-piracy efforts. With relative ease the Court has issued temporary restraining and seizure orders. If these hold up, more sites may be targeted in a similar fashion.

This outlook may also be the reason for CloudFlare to have their say in the matter. As a service provider to some of the largest piracy havens, including The Pirate Bay, there’s a lot at stake.
